RADIATOR.

Application filed June 28, 1920. Serial No. 392,595.

(GRANTED UNDER THE PRGVISIONS OF THE ACT OF MARCH 8, 1921, 41 STAT. L, 1313.)

To all whom. it may concern.

Be it known that I, Huoo J UNKERS, a citizen of Germany. residing at Dessau, Germany, have invented certain new and useful Improvements in Radiators (for which I have filed application in Germany on February 25, 1918, and Netherlands on June 19, 1919), of which the following is a specification.

This invention relates to the arrangement of the radiator in motor-driven vehicles and quite especially in flying machines.

According to this invention I arrange the radiator in front of a jacket serving to guide the air, for instance in front of the motor bonnet or the body envelope. in such a man ner, that the air leaving the radiator is deflected laterally by said jacket. I further attach to the side walls of the radiator and preferably to the vertical rear edges of the same adjustable flaps extending rearwardly. By varying the position of these flaps the cross-sectional area of the passage for the air lea-ring the radiator be-tween the guiding jacket and the flaps can be altered for'the Fig. 1 is a vertical longitudinal section on the line .lI-II in Fig. 2 of the front portion of the flying machine body.

Fig. 2 is a cross-section on the line I-I in Fig. l.

Fig. 3,is a horizontal section on the line III-.-III in Fig. 1.

a is the flying machine body and 7) is one of the cylinders of the motor carried thereon. c is the radiatorarranged between the motor hood (Z and the propeller c. The motor hood (Z deflects the air passing through the radiator, towards both sides. as indicated by the arrows in Fig. 3. To the side Walls f of the radiator flaps g are pivotally attached by means of hinges it. These flaps can be adjusted, preferably from the operators seat, by means of suitable means i, so

that the cross-section of the air-passage hetween the flaps and the motor hood d or the body envelope can be regulated.

I claim r 1. In a motor driven vehicle in combination, an envelope arranged on the front portion of said vehicle, a radiator arranged in front of said envelope in such a manner that the air after having passed through said radiator, is deflected sideways by said envelope and adjustable means to the rear of said radiator for varying the cross-sectional area of the passage for the deflected air.

2. In a motor driven vehicle in combination a motor arranged on the front portion of said vehicle, a hood surrounding said motor, a radiator arranged in front of said hood in such a manner that the air after having passed through said radiator is deflected sideways by said hood and adjustable flaps to the rear of said radiator adapted to vary the cross-sectional area of the passage for the deflected air.

In testimony whereof I atfix my signature.
